I’m encountering a weird situation where I also can’t replace the menu graphics. When I go to the page, I don’t seem to have this Display in Course Menu, when I go to the page? I’ve added screenshots below so you can see I’m using the course page list component.
Any help would be greatly appreciated. Thanks so much.
From the first screenshot it looks like you haven’t actually chosen a page to act as the course menu page.
Typically that would be the page you’ve added the Course Page List element to. Go to that page and in Settings toggle the Set as Course Menu setting on.
Once you’ve chosen a page to be the course menu page, you’ll see additional settings in the Topic 4: Quiz page settings.
